All 15 episodes of The Lost Planet (1953), Gunfighters of the Northwest (1954), Adventures of Captain Africa (1955), Perils of the Wilderness (1956), Captain Video (1951), and Mysterious Island (1951) were renewed.

Couldn't find any renewals for The Invisible Monster (1950), but it may have been renewed before 1978.

I found renewals for episodes 12, 13, 14 & 15 of Pirates of the High Seas (1950). The other episodes may have been renewed before 1978.

All 12 episodes of The Man with the Steel Whip (1954), Government Agents vs Phantom Legion (1951), and Panther Girl of the Kongo (1955) were renewed.

Thanks Bill, again it is kind of disappointing that so few are PD. Most of these I'm sure the studios will never do anything with. I've got several others that I already have conformation on as being PD that I'll try to post soon.
